What size PRV ?

(Spirit Lake)

Hello Thanks for your page. I have a model 47065 Harbor freight air compressor its a 21 gallon 125 psi unit. I needed a direct connection to the tank to run my double hammer air wrench. In installing the tee on the tank fitting somehow the PRV developed an internal leak. The number 8 is printed on it. I probably can get one local and avoid the shipping any ideas
